As importantly, the antioxidants and other health benefits of tea tend to be extracted more quickly than the caffeine. Caffeine is extracted over time, and so the first 30 seconds of a five minute steeping cycle may only extract 20 to 30% of the caffeine (the amount depends on the leaf and processing style). The truth, however, is something else entirely. The theory is that most of the caffeine is washed away in this initial steeping. It still contains about 5-10 mg per cup.Ī common myth is that you can "make your own" decaf tea by briefly steeping the tea and throwing away resulting liquor.
THEINE CAFFEINE FREE
Decaffeinated tea, in fact, is not caffeine free at all. A common misconception is that those who are caffeine intolerant should stock up on Decaf tea. Caffeine tolerance varies greatly among individuals, with some being much more caffeine sensitive than others. There has been much concern in the United States recently about the possible dangers of caffeine.
In fact, most sodas have more caffeine as well. In comparison, the same volume of coffee yields at least double the amount of caffeine. This is also true of very fine loose tea. old growth) make the following teas stand out in their class:Īlso, keep in mind that, because tea bags contain broken leaves of smaller size, they produce an infusion with more caffeine than loose tea does. assamica), growing methods (shade or high grown vs. Black tea, the varieties used (sinensis vs. While it's difficult (and usually incorrect) to make broad factual statements about how much caffeine is in Green Tea vs. There is no scientific basis to this common myth, and it results simply from measuring the caffeine in the cup after typical brewing methods and incorrectly crediting those results to the tea itself. Let's be clear: Oxidation does NOT increase the amount of caffeine in tea. But a tea steeped for five minutes in boiling water is going to transfer a LOT more caffeine to the cup than a tea steeped for two minutes at 180 degrees Fahrenheit. Black, Oolong, Green and White tea leaves themselves have surprisingly similar caffeine content. The greatest impact on caffeine content is the water temperature and length of steeping time. The youngest leaves, highest on the plant, contain the greatest concentration of caffeine AND antioxidants. Studies also show that leaf location on the tea plant affects content of caffeine in that tea. The amount of caffeine in tea depends on a number of factors, including the method and length of brewing or steeping. It found that the average caffeine level in the cups of tea (black English style teas) was 40mg vs 105mg in the average cup of drip coffee. A widely cited 2004 British study looked at 200 cups prepared by consumers going about their normal brewing routines.
After all, we normally use 2 grams of tea per 6 ounce cup, and 10 grams of coffee for the same quantity of water. While this is true when measuring coffee and tea in its dry form, this is false when comparing brewed coffee and tea. The biggest myth about the caffeine content between coffee and tea is that tea contains more caffeine than coffee.
